The San Juan River waters have experienced deterioration due to poor management of its basin. To address the issues, action has been taken to implement IWRM to address the areas of water, soil, forests and municipal development in a cross-sectoral manner. This case study is a good reminder of the integrated nature of IWRM, and the importance of a model that accounts for management of both water and land.
The area around Lake Moyua is experiencing severe soil degradation resulting from inappropriate agricultural practices. To reverse and control the degradation process, an IWRM Plan is implemented. By involving the communities, the aim is to restore the soil, the hydrological systems, forests and biodiversity, as well as the harmonisation of policies and implementation of management regulations. This case study consequently demonstrates the value of a bottom-up approach.
The Maltese islands experience acute water shortage as an area. To address this, leakage control has been developed to become a strategically important component for water resource management, and has been used to reach an optimum economic balance between water supply and water demand. The key lesson is that leakage management is an effective supply side action to increase efficiency in water use leading, and can be used as a strategic tool.
Egypt’s water resources are severely constrained. This calls for increasing the water use efficiency by improving irrigation management practice, as the agriculture sector is the main user of water resources. To address the issue, an Irrigation Improvement Programme was initiated, including a combination of technical changes and infrastructure investment. The case clearly demonstrates the importance of building appropriate institutional structures in parallel to the introduction of technical changes.
Due to the growing build-up area and changing land use in the Veluwe nature conservation area, the old water management infrastructure no longer coped. Action was thus taken and the traditional technical solution was replaced by a new integrated approach, which combines nature and landscape conservancy with modern water management. This case highlights the importance of utilising inhabitants’ knowledge when drafting new projects.
Climate change is expected to severely affect water resources in the low-lying part of the Netherlands. It was decided to take an integrated approach and a process was set up in which all parties claiming space in the area were invited to discuss the water issues. The key insight from this case is the additional water needs can be integrated in the spatial planning through an open planning process.
The EU Water Framework Directive requires measures to achieve good status of all waters by 2015. In Germany, it is not the federal government that is in charge of implementation but it is the responsibility of the county. To meet the objective, transboundary exchange of experiences was promoted by broadening the range of methods and tools available to water managers. From this study, it is evident that interaction with stakeholders plays a central role.
Astien groundwater aquifer has been subjected to over-use due to good water quality and over-extraction. To address this, SMETA, a syndicate of local authorities, was established to organise the management of the aquifer. Key lesson learnt is that an organisation like SMETA can prove to be a successful forum for groundwater protection.
In Ukraine, reforms in the sector of water supply and sanitation have focused on centralising water supply and sanitation. Efforts have been made to decentralise water management, delegate to local authorities as well as increase supply in rural areas. This has been done through awareness campaigns, capacity building and innovative techniques of wastewater reuse. The key lesson learnt from this case is that IWRM principles need to be considered when planning for water infrastructure.
The Danube region is characterised by long-term cooperation. One of the most important agreements is the Danube River Protection Convention, aiming to achieve sustainable and equitable water management. To achieve this, the Danubian countries have taken appropriate legal, administrative and technical measures to at least maintain and improve the ecological and water quality conditions. The main lesson learnt is that strong cooperation among all the involved parties is required.
